A misfiring engine will cause, low gas mileage, low power output, increased emissions and possible internal engine damage if left untreated. Typically an engine misfire under load, will be a problem with the ignition system, while low engine speed problems will be a vacuum, fuel management or compression issue.
Coral colonies grow through a form of asexual reproduction known as budding, in which polyps divide themselves to form new polyps . Corals can also reproduce sexually by spawning, which in Platygyra daedalea involves the release of gametes into the water, for external fertilisation. Platygyra daedalea is hermaphroditic, meaning that each polyp produces both eggs and sperm.
A coral head is a colony of myriad genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in length. A set of tentacles surround a central mouth opening.An exoskeleton is excreted near the base.hese are commonly known as zooxanthellae and the corals that contain them are zooxanthellate corals. Such corals require sunlight and grow in clear, shallow water, typically at depths shallower than 60 metres (200 ft).
